The effect of initiating neuraxial analgesia service on the rate of cesarean delivery in Hubei, China: a 16-month retrospective study.

BACKGROUND: No Pain Labor &Delivery (NPLD) is a nongovernmental project to increase access to safe neuraxial analgesia through specialized training. This study explores the change in overall cesarean delivery (CD) rate and maternal request CD(MRCD) rate in our hospital after the initiation of neuraxial analgesia service (NA). METHODS: NA was initiated in May 1st 2015 by the help of NPLD. Since then, the application of NA became a routine operation in our hospital, and every parturient can choose to use NA or not. The monthly rates of NA, CD, MRCD, multiparous women, intrapartum CD, episiotomy, postpartum hemorrhage (PPH), operative vaginal delivery and neonatal asphyxia were analyzed from January 2015 to April 2016. RESULTS: The rate of NA in our hospital was getting increasingly higher from 26.1% in May 2015 to 44.6% in April 2016 (p < 0.001); the rate of CD was 48.1% (3577/7360) and stable from January to May 2015 (p>0.05), then decreased from 50.4% in May 2015 to 36.3% in April 2016 (p < 0.001); the rate of MRCD was 11.4% (406/3577) and also stable from January to May 2015 (p>0.05), then decreased from 10.8% in May 2015 to 5.7% in April 2016 (p < 0.001). At the same time, the rate of multiparous women remained unchanged during the 16 month of observation (p>0.05). There was a negative correlation between the rate of NA and rate of overall CD, r = - 0.782 (95%CI [- 0.948, - 0.534], p<0.001), and between the utilization rate of NA and rate of MRCD, r = - 0.914 (95%CI [- 0.989, - 0.766], p<0.001). The rates of episiotomy, PPH, operative vaginal delivery and neonatal asphyxia in women who underwent vaginal delivery as well as the rates of intrapartum CD, neonatal asphyxia, and PPH in women who underwent CD remained unchanged, and there was no correlation between the rate of NA and anyone of those rates from January 1st 2015 to April 30th 2016 (p>0.05). CONCLUSIONS: Our study shows that the rates of CD and MRCD in our department were significantly decreased from May 1st 2015 to April 30th 2016, which may be due to the increasing use of NA during vaginal delivery with the help of NPLD.

[Planned home birth in Brazil: a systematic review]. / Parto domiciliar planejado no Brasil: uma revisão sistemática nacional.

Planned home birth (PHB) has grown in Brazil, especially in large urban centers, in the face of women's dissatisfaction with the current obstetric system. International studies have demonstrated the security of PHB, but national production about this area is still limited. Thus, this study aimed to review the national bibliographic production about PHB between 2008 and 2018, in order to compile data related to PHB in Brazil. After survey, 18 studies were included in the review, and then subdivided into the following categories: "Maternal and neonatal outcomes of PHB", "Feelings, motivation and personal characteristics of women that choose PHB", "Perception of professionals that practice PHB" and "Theoretical approach to PHB". It was concluded that the PHB has grown between privileged portions of Brazilian population, representing the important practice of women's autonomy, presenting itself as a safe alternative place of birth, with a high degree of satisfaction of women and families. However, this model of assistance presents itself as a limited option, since the PHB is not offered by the Health System, still unaccessible to most of women in the country.

O parto domiciliar planejado (PDP) tem crescido cada vez mais no Brasil, especialmente nos grandes centros urbanos, frente à crescente insatisfação das mulheres com o sistema obstétrico hospitalar vigente. Estudos internacionais demonstram a segurança do PDP, porém a produção nacional ainda é limitada nesta área. Desta maneira, este estudo objetivou revisar a produção bibliográfica nacional acerca de parto domiciliar entre os anos de 2008 e 2018, a fim de compilar dados relacionados ao PDP no Brasil. Após levantamento, 18 estudos foram incluídos na revisão, sendo subdivididos nas seguintes categorias: "Desfechos maternos e neonatais dos PDP", "Sentimentos, motivação e perfis associados à escolha pelo PDP", "Percepção dos profissionais que atendem PDP" e "Abordagem teórica do PDP". Concluiu-se que o PDP tem crescido entre parcelas privilegiadas da população, representando importante prática de exercício da autonomia da mulher em contraponto ao modelo obstétrico vigente, apresentando-se como alternativa segura de local de parto, com alto grau de satisfação para as mulheres e famílias. Este modelo de assistência, entretanto, apresenta-se como opção limitada, uma vez que o PDP não é oferecido pelo Sistema Único de Saúde, ainda inacessível para a maioria das mulheres no país.

Midwife-led care and obstetrician-led care for low-risk pregnancies: A cost comparison.

OBJECTIVE: Low-risk pregnant women cared for by midwives have similar birth outcomes to women cared for by physicians, although experiencing fewer medical procedures. However, limited research has assessed cost implications in the United States. Using national data, we assessed costs and resource use of midwife-led care vs obstetrician-led care for low-risk pregnancies using a decision-analytic approach. METHODS: We developed a decision-analytic model of costs (health plan payments to clinicians) and use of medical procedures during childbirth (epidural analgesia, labor induction, cesarean birth, episiotomy) and outcomes of care (birth at preterm gestation) that may differ with midwife-led vs obstetrician-led care. Model parameters for obstetric procedures were generated using Listening to Mothers III data, a national survey of women who gave birth in US hospitals in 2011-2012 and other published estimates. Cost estimates came from published or publicly available information on health insurance claims payments. RESULTS: The costs of childbirth for low-risk women with midwife-led care were, on average, $2262 less than births to low-risk women cared for by obstetricians. These cost differences derive from lower rates of preterm birth and episiotomy among women with midwife-led care, compared with obstetrician-led care. Across the population of US women with low-risk births each year (approximately 2.6 million), the model predicted substantially fewer preterm births (167 259 vs 219 427 for midwife-led vs obstetrician-led care) and fewer episiotomies (170 504 vs 415 686, for midwife-led vs obstetrician-led care). CONCLUSIONS: A shift from obstetrician-led care to midwife-led care for low-risk pregnancies could be cost saving.

[Rate of episiotomy in the University Clinical Hospital of Arrixaca and factors that influence in its practice.] / Tasa de episiotomía en el Hospital Clínico Universitario de La Arrixaca y factores que influyen en su práctica.

OBJECTIVE: The conduction of episiotomy is a questioned practice given the strong scientific evidence on its adverse effects. The study objectives were to know the episiotomy rate and its adaptation to the recommendations of the Ministry of Health, Consumption and Social Welfare and assess the associated factors. METHODS: It has been made a Observational, descriptive and transversal quantitative study, it was carried out in the university clinical hospital arrixaca. Data were collected from deliveries attended between January 1, 2016 and October 30, 2017, obtaining a sample of 10,630 women, registered in the SELENE computer program which is the clinical database of said hospital. To perform the data analysis, were used the SPSS statistical program and an Excel database. At the first level, it was carried out a descriptive analysis of the obstetric variables and, at a second level, the data were compared with the Ministry of Health indicators by means of a comparison of two proportions and the chi-square test. In order to estimate the Effect Size, the Cramer V was used for qualitative variables and the relative risk was calculated for each pair of qualitative variablesas a relative measure of the effect, to determine the strength of association between the variables. RESULTS: The episiotomy rate was 36.5%. When the birth started spontaneously, the percentage was 35.5%, when it was induced 47.2% and stimulated rate was 42.3%. The rate in eutocic deliveries was 20.6% and in instrumented was 95.25%. In primiparas, the episiotomy was 49.64% and in multiparas the conduction was 15.55%. Was observed a tendency of second-degree tears (43.40%), followed by first-degree (35.61%) and third-degree (19.81%) with episiotomy. CONCLUSIONS: The episiotomy rate in our study exceeds current recommendations. The variables associated with the performance of the episiotomy are induced or stimulated delivery, instrumentation and primiparity. There is a significant relationship between the practice of episiotomy and the greater degree of tear.

OBJETIVO: La realización de episiotomías es una práctica cuestionada dada la fuerte evidencia científica existente sobre sus efectos adversos. Los objetivos de este estudio fueron conocer la tasa de episiotomías y su adecuación a las recomendaciones del Ministerio de Sanidad, Consumo y Bienestar Social y valorar los factores asociados. METODOS: Se realizó un estudio cuantitativo observacional, descriptivo y transversal, que fue llevado a cabo en el Hospital Clinico Universitario Arrixaca. Se recogieron datos De los partos atendidos entre el 1 de enero de 2016 y el 30 de octubre de 2017, obteniendo una muestra de 10.630 mujeres, a través del programa informático SELENE, que es la base de datos clínicos de dicho hospital. Para realizar el análisis de datos se utilizó el programa estadístico SPSS y una base de datos Excel. En un primer nivel, se efectuó un análisis descriptivo de las variables obstétricas y, en un segundo nivel, se contrastaron los datos con los indicadores del Ministerio de Sanidad, Consumo y Bienestar Social mediante una comparación de dos proporciones y el test de la ji al cuadrado. Para poder estimar el Tamaño del Efecto se utilizó la V de Cramer para variables cualitativas, y se calculó el riesgo relativo para cada par de variables cualitativas como medida relativa del efecto, para determinar así la fuerza de asociación entre las variables. RESULTADOS: La tasa de episiotomías fue del 36,5%. Cuando el parto comenzó espontáneamente el porcentaje fue del 35,5%; cuando fue inducido, la tasa fue del 47,2% y cuando fue estimulado, el porcentaje fue del 42,3%. La tasa en partos eutócicos fue del 20,6% y en instrumentados fue del 95,25%. En primíparas, la realización de episiotomía fue del 49,64% y en multíparas la realización fue del 15,55%. Se observó una tendencia a desgarros de segundo grado (43,40%), seguidos de primer grado (35,61%) y de tercer grado (19,81%) con episiotomía. CONCLUSIONES: La tasa de episiotomía de nuestro estudio supera las actuales recomendaciones. Las variables asociadas a la realización de la episiotomía son el parto inducido o estimulado, la instrumentación y la primiparidad. Se evidencia una relación significativa entre la práctica de episiotomia y el mayor grado de desgarro.

Physician age and the abandonment of episiotomy.

OBJECTIVE: To determine whether women treated by older physicians are more likely to undergo episiotomy. DATA SOURCES/STUDY SETTING: Hospital discharge data from Pennsylvania for the period 1994 to 2010. STUDY DESIGN: We examined the impact of the year in which physicians started delivering babies (a proxy for age) in Pennsylvania on episiotomy rates using a linear probability model with hospital fixed effects. DATA COLLECTION/EXTRACTION METHODS: Using diagnosis and procedure codes, we identified women delivering vaginally (N = 1 658 327) and determined the proportion who had an episiotomy. PRINCIPAL FINDINGS: The average physician-level episiotomy rate declined from 54 percent in 1994 to 13 percent in 2010. Rates declined among older and younger physicians, but, at any point in time, women treated by older physicians were more likely to have an episiotomy. A 10-year difference in physician age is associated with a 6 percentage point increase in episiotomy rates. CONCLUSIONS: Results indicate that older physicians, who entered practice when episiotomy was common, were slow to adjust their practices in response to evidence showing that routine episiotomy is unnecessary.

[The extent of the implementation of reproductive health strategies in Catalonia (Spain) (2008-2017)]. / Alcance de la implementación en Cataluña de las estrategias de salud reproductiva (2008-2017).

OBJECTIVE: We analyse how reproductive health strategies have been incorporated into the everyday activities of the services and the resulting transformation of professional and user practices. METHOD: Cartographic research taking a multi-sited ethnographic approach that seeks to reveal the processes of transformation. Data generation techniques featuring participant observation and situated interviews. Discourse analysis of the text corpus using three analytical axes based on three main lines of action promoted by the strategies. RESULTS: We identified transformations in: 1) demedicalisation: an increase in midwives' know-how and autonomy, changes in episiotomy practice and the facilitation of bonding practices; 2) warmth of care: incorporation of women's needs and expectations and improvements in the comfortableness of birth settings, especially in assistance at physiological birth; and 3) participation: actions that foster shared decision-making and the involvement of the persons accompanying women in labour. CONCLUSIONS: Above all, transformation is visible in the incorporation of new attitudes, sensibilities and practices that have developed around the old structures, especially during physiological childbirth. The more technological areas have been less permeable to change. Risk management in decision-making and addressing diversity are identified as areas where transformation is less evident.

Outcomes of childbearing Medicaid beneficiaries engaged in care at Strong Start birth center sites between 2012 and 2014.

BACKGROUND: Variations in care for pregnant women have been reported to affect pregnancy outcomes. METHODS: This study examined data for all 3136 Medicaid beneficiaries enrolled at American Association of Birth Centers (AABC) Center for Medicare and Medicaid Innovation Strong Start sites who gave birth between 2012 and 2014. Using the AABC Perinatal Data Registry, descriptive statistics were used to evaluate socio-behavioral and medical risks, and core perinatal quality outcomes. Next, the 2082 patients coded as low medical risk on admission in labor were analyzed for effective care and preference sensitive care variations. Finally, using binary logistic regression, the associations between selected care processes and cesarean delivery were explored. RESULTS: Medicaid beneficiaries enrolled at AABC sites had diverse socio-behavioral and medical risk profiles and exceeded quality benchmarks for induction, episiotomy, cesarean, and breastfeeding. Among medically low-risk women, the model demonstrated effective care variations including 82% attendance at prenatal education classes, 99% receiving midwifery-led prenatal care, and 84% with midwifery- attended birth. Patient preferences were adhered to with 83% of women achieving birth at their preferred site of birth, and 95% of women using their preferred infant feeding method. Elective hospitalization in labor was associated with a 4-times greater risk of cesarean birth among medically low-risk childbearing Medicaid beneficiaries. CONCLUSIONS: The birth center model demonstrates the capability to achieve the triple aims of improved population health, patient experience, and value.

[Assessment of restrictive episiotomy use and impact on perineal tears in the Burgundy's Perinatal Network]. / Évaluation de la pratique restrictive de l'épisiotomie et de l'impact sur les déchirures périnéales au sein du Réseau périnatal de Bourgogne.

OBJECTIVES: To analyse episiotomy and perineal tears rates in Burgundy after French National College of Obstetricians and Gynecologists (CNGOF) guidelines in 2005. MATERIALS AND METHOD: Multicenter retrospective study, between 2003-2005 (period 1) et 2012-2014 (period 2), conducted on singletons vaginal deliveries, in cephalic presentation from 37 weeks. We compared the episiotomy rate (ER), and perineal lesions in normal deliveries (ND) and instrumental deliveries (ID) between the two periods. RESULTS: A total of 74,268 women were included. The overall ER significantly decreased from 35.8 to 16.7% (P<0.01), without increasing third degree perineal tears (0.73% vs. 0.66%) or fourth degree (0.14% vs 0.14%). First degree perineal tears rose (42.1% vs 17.6%, P<0.001), second degree decreased (13.5% vs 20.5%, P<0.001). ER decreased whatever the level of motherhood, healthcare ward, vaginal delivery type, or the instrument used. CONCLUSION: Our study found a strong impact in Burgundy of the French guidelines for the practice of restrictive episiotomy for both ND and for ID without increasing sphincter tears and in decreasing spontaneous morbidity.

Midwife-led continuity models versus other models of care for childbearing women.

BACKGROUND: Midwives are primary providers of care for childbearing women around the world. However, there is a lack of synthesised information to establish whether there are differences in morbidity and mortality, effectiveness and psychosocial outcomes between midwife-led continuity models and other models of care. OBJECTIVES: To compare midwife-led continuity models of care with other models of care for childbearing women and their infants. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (25 January 2016) and reference lists of retrieved studies. SELECTION CRITERIA: All published and unpublished trials in which pregnant women are randomly allocated to midwife-led continuity models of care or other models of care during pregnancy and birth. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. The quality of the evidence was assessed using the GRADE approach. MAIN RESULTS: We included 15 trials involving 17,674 women. We assessed the quality of the trial evidence for all primary outcomes (i.e. regional analgesia (epidural/spinal), caesarean birth, instrumental vaginal birth (forceps/vacuum), spontaneous vaginal birth, intact perineum, preterm birth (less than 37 weeks) and all fetal loss before and after 24 weeks plus neonatal death using the GRADE methodology: all primary outcomes were graded as of high quality.For the primary outcomes, women who had midwife-led continuity models of care were less likely to experience regional analgesia (average risk ratio (RR) 0.85, 95% confidence interval (CI) 0.78 to 0.92; participants = 17,674; studies = 14; high quality), instrumental vaginal birth (average RR 0.90, 95% CI 0.83 to 0.97; participants = 17,501; studies = 13; high quality), preterm birth less than 37 weeks (average RR 0.76, 95% CI 0.64 to 0.91; participants = 13,238; studies = eight; high quality) and less all fetal loss before and after 24 weeks plus neonatal death (average RR 0.84, 95% CI 0.71 to 0.99; participants = 17,561; studies = 13; high quality evidence). Women who had midwife-led continuity models of care were more likely to experience spontaneous vaginal birth (average RR 1.05, 95% CI 1.03 to 1.07; participants = 16,687; studies = 12; high quality). There were no differences between groups for caesarean births or intact perineum.For the secondary outcomes, women who had midwife-led continuity models of care were less likely to experience amniotomy (average RR 0.80, 95% CI 0.66 to 0.98; participants = 3253; studies = four), episiotomy (average RR 0.84, 95% CI 0.77 to 0.92; participants = 17,674; studies = 14) and fetal loss less than 24 weeks and neonatal death (average RR 0.81, 95% CI 0.67 to 0.98; participants = 15,645; studies = 11). Women who had midwife-led continuity models of care were more likely to experience no intrapartum analgesia/anaesthesia (average RR 1.21, 95% CI 1.06 to 1.37; participants = 10,499; studies = seven), have a longer mean length of labour (hours) (mean difference (MD) 0.50, 95% CI 0.27 to 0.74; participants = 3328; studies = three) and more likely to be attended at birth by a known midwife (average RR 7.04, 95% CI 4.48 to 11.08; participants = 6917; studies = seven). There were no differences between groups for fetal loss equal to/after 24 weeks and neonatal death, induction of labour, antenatal hospitalisation, antepartum haemorrhage, augmentation/artificial oxytocin during labour, opiate analgesia, perineal laceration requiring suturing, postpartum haemorrhage, breastfeeding initiation, low birthweight infant, five-minute Apgar score less than or equal to seven, neonatal convulsions, admission of infant to special care or neonatal intensive care unit(s) or in mean length of neonatal hospital stay (days).Due to a lack of consistency in measuring women's satisfaction and assessing the cost of various maternity models, these outcomes were reported narratively. The majority of included studies reported a higher rate of maternal satisfaction in midwife-led continuity models of care. Similarly, there was a trend towards a cost-saving effect for midwife-led continuity care compared to other care models. AUTHORS' CONCLUSIONS: This review suggests that women who received midwife-led continuity models of care were less likely to experience intervention and more likely to be satisfied with their care with at least comparable adverse outcomes for women or their infants than women who received other models of care.Further research is needed to explore findings of fewer preterm births and fewer fetal deaths less than 24 weeks, and all fetal loss/neonatal death associated with midwife-led continuity models of care.

Do we know enough? A quality assessment of the Finnish intervention to prevent obstetric anal sphincter injuries.

OBJECTIVE: Especially in the Nordic countries, increases in obstetric anal sphincter injuries (OASIS) have prompted standard use of the Finnish intervention for their prevention. We performed a quality assessment of the introduction of the intervention in a Danish hospital setting. METHODS: All vaginal deliveries by primiparous women the year before (N = 343) and after (N = 334) the introduction were compared in a retrospective, observational design. Fisher's exact test, Student's t-test, and multiple logistic regression analysis were performed. RESULTS: No significant difference in OASIS (OR: 0.5; 95% CI: 0.3-1.1) was found. The post-implementation group saw a significant increase in episiotomy (OR: 1.8; 95% CI: 1.1-2.9) and the length of second stage labor (p < 0.05) while intact perineum (OR: 0.5; 95% CI: 0.3-0.9), use of upright positions for birth (OR: 3.2; 95% CI: 1.8-5.5), and neonatal blood gas levels were significantly reduced (p < 0.05). CONCLUSIONS: Introduction of the Finnish intervention was not followed by a significant reduction of OASIS, but a downward trend was seen. The study results raise questions about potential side effects of the Finnish intervention on neonatal outcomes, intact perineum, and women's free choice of birth positions. More knowledge on effect and side effects from high-evidence studies are needed.

Midwife-led continuity models versus other models of care for childbearing women.

BACKGROUND: Midwives are primary providers of care for childbearing women around the world. However, there is a lack of synthesised information to establish whether there are differences in morbidity and mortality, effectiveness and psychosocial outcomes between midwife-led continuity models and other models of care. OBJECTIVES: To compare midwife-led continuity models of care with other models of care for childbearing women and their infants. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 May 2015) and reference lists of retrieved studies. SELECTION CRITERIA: All published and unpublished trials in which pregnant women are randomly allocated to midwife-led continuity models of care or other models of care during pregnancy and birth. DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and checked them for accuracy. MAIN RESULTS: We included 15 trials involving 17,674 women. We assessed the quality of the trial evidence for all primary outcomes (i.e., regional analgesia (epidural/spinal), caesarean birth, instrumental vaginal birth (forceps/vacuum), spontaneous vaginal birth, intact perineum, preterm birth (less than 37 weeks) and overall fetal loss and neonatal death (fetal loss was assessed by gestation using 24 weeks as the cut-off for viability in many countries) using the GRADE methodology: All primary outcomes were graded as of high quality.For the primary outcomes, women who had midwife-led continuity models of care were less likely to experience regional analgesia (average risk ratio (RR) 0.85, 95% confidence interval (CI) 0.78 to 0.92; participants = 17,674; studies = 14; high quality), instrumental vaginal birth (average RR 0.90, 95% CI 0.83 to 0.97; participants = 17,501; studies = 13; high quality), preterm birth less than 37 weeks (average RR 0.76, 95% CI 0.64 to 0.91; participants = 13,238; studies = 8; high quality) and less overall fetal/neonatal death (average RR 0.84, 95% CI 0.71 to 0.99; participants = 17,561; studies = 13; high quality evidence). Women who had midwife-led continuity models of care were more likely to experience spontaneous vaginal birth (average RR 1.05, 95% CI 1.03 to 1.07; participants = 16,687; studies = 12; high quality). There were no differences between groups for caesarean births or intact perineum.For the secondary outcomes, women who had midwife-led continuity models of care were less likely to experience amniotomy (average RR 0.80, 95% CI 0.66 to 0.98; participants = 3253; studies = 4), episiotomy (average RR 0.84, 95% CI 0.77 to 0.92; participants = 17,674; studies = 14) and fetal loss/neonatal death before 24 weeks (average RR 0.81, 95% CI 0.67 to 0.98; participants = 15,645; studies = 11). Women who had midwife-led continuity models of care were more likely to experience no intrapartum analgesia/anaesthesia (average RR 1.21, 95% CI 1.06 to 1.37; participants = 10,499; studies = 7), have a longer mean length of labour (hours) (mean difference (MD) 0.50, 95% CI 0.27 to 0.74; participants = 3328; studies = 3) and more likely to be attended at birth by a known midwife (average RR 7.04, 95% CI 4.48 to 11.08; participants = 6917; studies = 7). There were no differences between groups for fetal loss or neonatal death more than or equal to 24 weeks, induction of labour, antenatal hospitalisation, antepartum haemorrhage, augmentation/artificial oxytocin during labour, opiate analgesia, perineal laceration requiring suturing, postpartum haemorrhage, breastfeeding initiation, low birthweight infant, five-minute Apgar score less than or equal to seven, neonatal convulsions, admission of infant to special care or neonatal intensive care unit(s) or in mean length of neonatal hospital stay (days).Due to a lack of consistency in measuring women's satisfaction and assessing the cost of various maternity models, these outcomes were reported narratively. The majority of included studies reported a higher rate of maternal satisfaction in midwife-led continuity models of care. Similarly, there was a trend towards a cost-saving effect for midwife-led continuity care compared to other care models. AUTHORS' CONCLUSIONS: This review suggests that women who received midwife-led continuity models of care were less likely to experience intervention and more likely to be satisfied with their care with at least comparable adverse outcomes for women or their infants than women who received other models of care.Further research is needed to explore findings of fewer preterm births and fewer fetal deaths less than 24 weeks, and overall fetal loss/neonatal death associated with midwife-led continuity models of care.

Racial and ethnic disparities in maternal morbidity and obstetric care.

OBJECTIVE: To evaluate whether racial and ethnic disparities exist in obstetric care and adverse outcomes. METHODS: We analyzed data from a cohort of women who delivered at 25 hospitals across the United States over a 3-year period. Race and ethnicity was categorized as non-Hispanic white, non-Hispanic black, Hispanic, or Asian. Associations between race and ethnicity and severe postpartum hemorrhage, peripartum infection, and severe perineal laceration at spontaneous vaginal delivery as well as between race and ethnicity and obstetric care (eg, episiotomy) relevant to the adverse outcomes were estimated by univariable analysis and multivariable logistic regression. RESULTS: Of 115,502 studied women, 95% were classified by one of the race and ethnicity categories. Non-Hispanic white women were significantly less likely to experience severe postpartum hemorrhage (1.6% non-Hispanic white compared with 3.0% non-Hispanic black compared with 3.1% Hispanic compared with 2.2% Asian) and peripartum infection (4.1% non-Hispanic white compared with 4.9% non-Hispanic black compared with 6.4% Hispanic compared with 6.2% Asian) than others (P<.001 for both). Severe perineal laceration at spontaneous vaginal delivery was significantly more likely in Asian women (2.5% non-Hispanic white compared with 1.2% non-Hispanic black compared with 1.5% Hispanic compared with 5.5% Asian; P<.001). These disparities persisted in multivariable analysis. Many types of obstetric care examined also were significantly different according to race and ethnicity in both univariable and multivariable analysis. There were no significant interactions between race and ethnicity and hospital of delivery. CONCLUSION: Racial and ethnic disparities exist for multiple adverse obstetric outcomes and types of obstetric care and do not appear to be explained by differences in patient characteristics or by delivery hospital. LEVEL OF EVIDENCE: II.

Private health care coverage and increased risk of obstetric intervention.

BACKGROUND: When clinically indicated, common obstetric interventions can greatly improve maternal and neonatal outcomes. However, variation in intervention rates suggests that obstetric practice may not be solely driven by case criteria. METHODS: Differences in obstetric intervention rates by private and public status in Ireland were examined using nationally representative hospital discharge data. A retrospective cohort study was performed on childbirth hospitalisations occurring between 2005 and 2010. Multivariate logistic regression analysis with correction for the relative risk was conducted to determine the risk of obstetric intervention (caesarean delivery, operative vaginal delivery, induction of labour or episiotomy) by private or public status while adjusting for obstetric risk factors. RESULTS: 403,642 childbirth hospitalisations were reviewed; approximately one-third of maternities (30.2%) were booked privately. After controlling for relevant obstetric risk factors, women with private coverage were more likely to have an elective caesarean delivery (RR: 1.48; 95% CI: 1.45-1.51), an emergency caesarean delivery (RR: 1.13; 95% CI: 1.12-1.16) and an operative vaginal delivery (RR: 1.25; 95% CI: 1.22-1.27). Compared to women with public coverage who had a vaginal delivery, women with private coverage were 40% more likely to have an episiotomy (RR: 1.40; 95% CI: 1.38-1.43). CONCLUSIONS: Irrespective of obstetric risk factors, women who opted for private maternity care were significantly more likely to have an obstetric intervention. To better understand both clinical and non-clinical dynamics, future studies of examining health care coverage status and obstetric intervention would ideally apply mixed-method techniques.

Midwife-led continuity models versus other models of care for childbearing women.

BACKGROUND: Midwives are primary providers of care for childbearing women around the world. However, there is a lack of synthesised information to establish whether there are differences in morbidity and mortality, effectiveness and psychosocial outcomes between midwife-led continuity models and other models of care. OBJECTIVES: To compare midwife-led continuity models of care with other models of care for childbearing women and their infants. SEARCH METHODS: We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (28 January 2013) and reference lists of retrieved studies. SELECTION CRITERIA: All published and unpublished trials in which pregnant women are randomly allocated to midwife-led continuity models of care or other models of care during pregnancy and birth. DATA COLLECTION AND ANALYSIS: All review authors evaluated methodological quality. Two review authors checked data extraction. MAIN RESULTS: We included 13 trials involving 16,242 women. Women who had midwife-led continuity models of care were less likely to experience regional analgesia (average risk ratio (RR) 0.83, 95% confidence interval (CI) 0.76 to 0.90), episiotomy (average RR 0.84, 95% CI 0.76 to 0.92), and instrumental birth (average RR 0.88, 95% CI 0.81 to 0.96), and were more likely to experience no intrapartum analgesia/anaesthesia (average RR 1.16, 95% CI 1.04 to 1.31), spontaneous vaginal birth (average RR 1.05, 95% CI 1.03 to 1.08), attendance at birth by a known midwife (average RR 7.83, 95% CI 4.15 to 14.80), and a longer mean length of labour (hours) (mean difference (hours) 0.50, 95% CI 0.27 to 0.74). There were no differences between groups for caesarean births (average RR 0.93, 95% CI 0.84 to 1.02).Women who were randomised to receive midwife-led continuity models of care were less likely to experience preterm birth (average RR 0.77, 95% CI 0.62 to 0.94) and fetal loss before 24 weeks' gestation (average RR 0.81, 95% CI 0.66 to 0.99), although there were no differences in fetal loss/neonatal death of at least 24 weeks (average RR 1.00, 95% CI 0.67 to 1.51) or in overall fetal/neonatal death (average RR 0.84, 95% CI 0.71 to 1.00).Due to a lack of consistency in measuring women's satisfaction and assessing the cost of various maternity models, these outcomes were reported narratively. The majority of included studies reported a higher rate of maternal satisfaction in the midwifery-led continuity care model. Similarly there was a trend towards a cost-saving effect for midwife-led continuity care compared to other care models. AUTHORS' CONCLUSIONS: Most women should be offered midwife-led continuity models of care and women should be encouraged to ask for this option although caution should be exercised in applying this advice to women with substantial medical or obstetric complications.

Episiotomy rate in Vietnamese-born women in Australia: support for a change in obstetric practice in Viet Nam.

OBJECTIVE: To describe the use of episiotomy among Vietnamese-born women in Australia, including risk factors for, and pregnancy outcomes associated with, episiotomy. METHODS: This population-based, retrospective cohort study included data on 598 305 singleton, term (i.e. ≥ 37 weeks' gestation) and vertex-presenting vaginal births between 2001 and 2010. Data were obtained from linked, validated, population-level birth and hospitalization data sets. Contingency tables and multivariate analysis were used to compare risk factors and pregnancy outcomes in women who did or did not have an episiotomy. FINDINGS: The episiotomy rate in 12 208 Vietnamese-born women was 29.9%, compared with 15.1% in Australian-born women. Among Vietnamese-born women, those who had an episiotomy were significantly more likely than those who did not to be primiparous, give birth in a private hospital, have induced labour or undergo instrumental delivery. In these women, having an episiotomy was associated with postpartum haemorrhage (adjusted odds ratio, aOR: 1.26; 95% confidence interval, CI: 1.08-1.46) and postnatal hospitalization for more than 4 days (aOR: 1.14; 95% CI: 1.00-1.29). Among multiparous women only, episiotomy was positively associated with a third- or fourth-degree perineal tear (aOR: 2.00; 95% CI: 1.31-3.06); in contrast, among primiparous women the association was negative (aOR: 0.47; 95% CI: 0.37-0.60). CONCLUSION: Episiotomy was performed in far fewer Vietnamese-born women giving birth in Australia than in Viet Nam, where more than 85% undergo the procedure, and was not associated with adverse outcomes. A lower episiotomy rate should be achievable in Viet Nam.

[A policy of selective episiotomy in a ward: an example of medical professional assessment]. / Politique restrictive d'épisiotomie au sein d'un service : un exemple d'évaluation des pratiques professionnelles.

OBJECTIVES: To reduce the episiotomy rates, according to the Clinical Practice Guidelines, of 2005, from the French College of Obstetricians and Gynaecologists. PATIENTS AND METHODS: A cross sectional study was conducted, in the university hospital maternities (Maternity 1 and 2) with a retrospective record from medical files. Patients who had delivered in those maternities, by vaginal route, after 22 weeks amenorrhea were eligible. The global rate of episiotomy was analysed from 2006 to 2008. A descriptive clinical study was performed with a retrospective analysis (from July to December 2005 on 100 medical files and from July to December 2007 on 85 files). Besides, a study of episiotomy rate was conducted from 2006 to 2008. Improvement actions were developed between the two phases of assessment of the audit: sharing and comparing the results to standardized episiotomy rates, and elaborating an informatized regional perinatality file with episiotomy related items and national recommendations. RESULTS: Episiotomy rate decreased during the study, from 22.35% in 2005 to 19.34% in 2008, in the Ward 1 (p<0.0001) and from 33.62% in 2005 to 17.93% en 2008 (p<0.0001) in the Ward 2. An improvement was observed between the two periods of audits, for each item of the chart but without statistical signification. DISCUSSION AND CONCLUSION: Theses procedures have led to a positive impact on practices thanks to the work group and because of the politics of the perinatal network in favour of an episiotomy reduction. We hope these results could be improved in the future.

Comparative effectiveness research, technological abandonment, and health care spending.

PURPOSE: Policymakers hope that comparative effectiveness research will identify examples of widely used therapies that are no better than less expensive alternatives and, consequently, reduce health care spending. Comparative effectiveness research is unlikely to reduce spending if physicians are quick to adopt effective treatments but slow to abandon ineffective ones. METHODOLOGY/APPROACH: We present a theoretical model that shows how physicians will adopt new treatments in response to positive evidence more readily than they abandon existing treatments in response to negative evidence if the marginal costs of production decline post-adoption. We report trends in the use of two common procedures, percutaneous coronary intervention (PCI) for patients with stable angina and routine episiotomy in vaginal childbirth, where comparative effectiveness research studies have failed to find evidence of a benefit. FINDINGS: Use of PCI and episiotomy have declined over time but are still excessive based on the standards implied by comparative effectiveness research. PRACTICAL IMPLICATIONS (IF APPLICABLE): The findings suggest that comparative effectiveness research has the potential to reduce costs but additional efforts are necessary to fully realize savings from abandonment. ORIGINALITY/VALUE OF CHAPTER: There is a large literature on technological adoption in health care, but few studies address technological abandonment. Understanding abandonment is important for efforts to decrease health care costs by reducing use of ineffective but costly treatments.

Obstetric profiles of foreign-born women in Western Australia using data linkage, 1998-2006.

BACKGROUND: Despite Western Australia (WA) having the highest proportion of overseas-born residents of any Australian state, no previous study has examined the general patterns of obstetric health of foreign-born women in WA. AIMS: To examine the obstetric profiles of foreign-born women in WA using routinely collected perinatal data. METHODS: The records of 59,245 confinements to foreign-born women were compared with those of 149,737 Australian-born, non-Indigenous women in WA between 1998 and 2006 using chi-square tests and ANOVA procedures. RESULTS: Foreign-born women were generally older, more likely to be married and have partners in highly skilled occupations, and were less likely to have private insurance or be teenage mothers. They were more commonly grand multiparae and were more likely to give birth at age 35 or older. On average, foreign-born women experienced increased risk of gestational diabetes, pre-labour rupture of membranes, failure to progress, fetal distress, perineal laceration and post-partum haemorrhage. They were less likely to have an induced labour and more likely to use fetal monitoring. Instrumental delivery, episiotomy and caesarean sections varied with maternal region of origin. CONCLUSIONS: Several important differences in the obstetric profiles of foreign-born women were found. These differences have useful implications for obstetric services in culturally and linguistically diverse populations. Collection of further variables would also benefit the future provision of equitable and culturally appropriate care to diverse immigrant groups.
